| Abstract: | In this paper, the gas phase proton affinity ( PA ) of aliphatic amines, alcohols and ethers is expressed as a function of the atomic charge qX(X = N or O atom) , the Polarizability Effect Index ( PEI) of alkyl group and the hybrid sp3 orbital energy EX(sp3) (X= N or O atom): PA(kJ/mol) = 2383.5547 - 1060.3351qX 59.4247PEI - 117.0142EX(sp3) . This novel general formula can better elucidate the change rule of PA for the title compounds. |
